  1. The rod is naturally MUCH stronger in compression - its the weakest in tension when its trying to throw the piston off the rod at the end of the exhaust / beginning intake stroke at maximum RPM. This is why the diesel rod is so badly - it never has to rev very high, yet it experiences a much higher compression ratio and combustion pressures than the petrol - this is why diesel engines are cast iron. Quote "The 5.2-liter V10 that debuted in the 2009 Audi R8 has the highest mean piston speed for any production car (26.9 m/s) " " high speed diesel ~14–17 m/s for automobile engines"

  2.  @michele-janemotte7337  - If you are going to be wrong - try not to be abusive with it.

  3. those old BMW engines were astonishing

  4.  @Fincher123  I believe bent conrods are usually when the engine hydraulics.

  5. EVERYONE IN THE COMMENTS SAYING IT NEEDS TO BE IN COMPRESSION here are the facts: The rod is naturally MUCH stronger in compression - its the weakest in tension when its trying to throw the piston off the rod at the end of the exhaust / beginning intake stroke at maximum RPM. This is why the diesel rod does so badly - it never has to rev very high, yet it experiences a much higher compression ratio and combustion pressures than the petrol - this is why diesel engines are cast iron. Quote "The 5.2-liter V10 that debuted in the 2009 Audi R8 has the highest mean piston speed for any production car (26.9 m/s) " " high speed diesel ~14–17 m/s for automobile engines" CON RODS main failure is in TENSION, a compression failure usually occurs when hydraulic-ed or when the timing is advanced too much .

  9.  @69GROMINET  I think that is either the Gordon Murry T50 of the Aston Martin Valkyrie. For comparison "Formula 1 engines are actually around 26 m/s mean piston speed and 41 m/s maximum piston velocity at redline" So its probably about right - I think the bottom line is 26/27 m/s average is about the limits of the materials we have at the moment

  10.  @MrTL3wis  Correct. But where i lived in North Yorkshire hydraulic engines were quite common - lots of fords through rivers and flooding
